As I have told before, there are several methods for declaring an array in assembly language. Based and indexed addressing Javeria Yaqoob. I've searched the Forums but I get more confused as I dig deeper. If its an integer array then it needs to be sizeof(int) * 20 * 20 bytes, or 4*20*20 = 1600 bytes.How you store the data is pretty much up to you.
